Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).
Speed is exactly like velocity, except velocity has a fixed direction. So speed would be 50mph, whereas velocity would be 50mph NE
Velocity is a vector: it has a direction. The others are all scalars. The dimensions of the scalars are Speed : [LT-1] Time: [T] Distance: [L]
velocity is speed with a direction. speed would be like 35mph. velocity would be like 35 mph south
Velocity = Speed / Time So, in the context of a triangle, speed would be at the top.
A speedometer measures speed only and not velocity. Velocity is a measure speed of travel and the direction of travel. A GPS unit would measure velocity as it would measure both speed and direction of travel.
No, velocity is a vector quantity and measures both speed and direction. If the velocity of an object is constant then that would also mean the speed would stay constant.
Yes, velocity would be the vector companion of speed, as velocity must have a direction.
The speed of anything is measured in metres per second. The difference between speed and velocity is that velocity is a vector, that is it has direction and well as magnitude. So velocity would be measured in metres per second in a certain direction.
Yes. If you divide a distance by a time, you get a speed or a velocity. Actually, in physics this would be called a speed; a velocity would also include a direction. But in popular language, "speed" and "velocity" are used interchangeably.
That would be velocity
When the direction of motion is relevant, you would use velocity rather than speed.
the speed would have to change.
Velocity is speed with a direction. For Example 30 Miles/hour East would be velocity.
That would be velocity.
velocity is the speed at which you are traveling, acceleration is the rate you are increasing or decreasing in velocity. If you are going at constant velocity, you are not increasing or decreasing speed, therefore your acceleration would be zero.-@mikesbabygurl13@
Consider an object turning in a circle at a constant speed. Because velocity is not just the value of speed, but also the direction in which the object is moving, the velocity would not be constant.
Two position measurements and the time between the measurements will give the average velocity (i.e. speed and direction).
Velocity is a vector quantity, i.e. it consists of two measures, one is speed, the other is direction. If the speed remains constant then a change in direction would alter the velocity. (you didn't list any examples)
Speed, or velocity. For velocity you would also need a direction.
Well velocity is mass * acceleration, so if you add weight while keeping the same speed, that would be a change in velocity.
I would say vector
Velocity means speed or speediness. When you drive a car at 55 mph, that would be it's velocity. It does have an upper limit of velocity. It can also mean the rate of change in speed. You can also look at it as the speed that gets you get up to 55 mph.
Velocity includes both speed and direction, so velocity will change when an object changes direction while maintaining it's speed. An example is a car at constant speed around a curve.
Yes. Velocity is made up of speed and direction (i.e. 12mph North). So a car driving in a circle could have constant speed, but its velocity would be continually changing.
